IMPROVEMENT IN VARNISH FOR MAKING PRINTERS IN K"AND FOR OTHER PURPOSES.,

Specification forming part of Letters Patent No. 39,96Q, dated September 15, 1863.

.To all whom it may concern:

Be it known that 1, DAVID STEINERT,0fil1G free city of Hamburg, Germany, have discovered certain new and useful Improvements in Varnish for Making Printers Ink and for other. Purposes; and 1 do hereby declare that the following isafull and exactdescription ofthe same.

In this description I presume the reader to be already familiar with the art of manufacturing varnishes from ordinary materials, and with the difiiculties attending the substitution vof rock-oil (known as petroleum l for the linseed-oil formerly used.

1 use petroleum with success, and produce printers ink (black and colored) of excellent quality and well-drying oil-colors at a lower cost than the same quality can be produced by any other means known to me.

- It has long been known that petroleum will dissolve resinous gums and allow the incorporation of coloring-matter ,but the varnishes, inks, paints, &c., produced thereby have been all inferior in quality, or have cost more. in

their manufacture.

a clear and thick varnish of a reddish-brown color and very transparent. This varnish, on being grounditogether with the ordinary coloring-mat'tcr in sufficient quantity to give it the right consistcncysay one part of lampblack withtwo parts of the varnisl1,by weightand again agitated at a temperature of from 60 centigrade (140 Fahrenheit) to 80 centigrade, (176? Fahrenheit,) with the addition of from five per cent. to ten per cent. of the entire mass of common yellow soap, produces an ink ol' good quality adapted-for all kinds of printing, and possessing the property of dry- ;ing rapidly.

To make a varnish for oil-colors I add to one varnish two parts of refined petroleum, and add furthersoap, the quantity of the lat er now added'heing five per cent. of the entire. mass--i. 0., live per cent: of the combined varnish and petroleum, and expose the whole to a temperature of 80 centigrade, (176 Fahren hcit,) and agitate gently until the soap is dissolved and the fluid appears clear and transparent. I pass this thin varnish throughn't-hin filter-and grind it with colors in the ordinary manner, producingoil-colors of good quality, which may be applied to wood, stone, paper, and-all stuffs to which linseed-oil paint is applicable.

I have used other resins in the manner above described besides coinmon' rosin, and the effect has been very satisfactory. gum-arabic, and even gum-copal, in this man- 1fer,"and believe that all resinous gums may be used with good effect in the manufacture of this varnish.

and of the petroleum and soap each tothc other constituents within quite wide limits, and the changes in the proportions, as also in the quality, of the ingredients will afl'ect the properties of the varnish anchor? the compounds produced therefrom. In the production of inks for printing upon different kinds of materiahand with difl'erent systems of printin gas,for example,lithogra.phic stones, as distinthis variation of ingredients is of service, and may be performed as circumstances shall require, even to the extent of making the gum in some instances one-half the weight of the petroleum and in other instances double the weightof the petroleum. It the soap is reduced greatly in amount or omitted altogether in the thick varnish first. described, a very clear and desirable varnish is produced by operating in other respects as described; but the inks made therefrom will not dry quickly. I do not consider it expedient ever to omit the soapin the second--the thin varnish for oilcolors.

. It in the manufacture of thelatterl neglectto take the steps above described, and proceed to make it by the direct admixture and heating of the quantities of petroleum and rosin v prescribed, the product is not as good,by reason of its becoming turbid very easily.

part, by weight, of the above-described thick I have used" Icau change the proportions of the gum guished from metal types or wood -blocks-- iiOil-eolors for'ali kinds of painting prepared bythe several steps above described are much easier applied than linseed-oil colors, and yet dry quicker, without irnpairin g the durability.

The painting with these colors is of a richer gloss, and, at the present prices of materials,

mziybeeii'ected'with much iess expense'ihanwith linseed-oil colors. v

In painting with my improved material no siccatives need be added, Printers ink madegwith my improved material, though'it adheres very firmly'to the paper and is perfectly durable under all ordinary s the peculiar advantage that it conditions,

may be removed by treating .the paper with soda in a, grinding apparatus, and the paper reduced again to a white pulp, suitable for the manufactnreof more paper as white as before.

' {.fhisisa great advantage in the present scarcity of white material and high price of white paper. 7

My thick varnish, prepared as described, in-- dependently of the soap, is clear and permanent, and better adapted to'serve both the uses of receiving color for printers ink and receiving more petroleum and being converted into oil-paint than any varnish from'thes'e materials, orany other of equal moderate cost known to me, and by reason of the moderate heat employed the danger of fire is much less than with ordinary materials andordinary processcs anti ':nlyvarnisiiprepared therefrom by dilution and reheating, as described for oil-. colors, produces, by subsequent grinding with colors and .the addition specified, a better and quiekerdrying and more durable paint than any other of equally moderate cost known to me. I

witnesses My addition 0t soapin the manner and underihe conditions prescribed gives 'the vai nish, inks, and-paints a property of drying rap idly amTpert'ectly without detracting from the permanence and other desirablequalities of the goods, and at a costfor material and labor which is'very slight? What I claim as n yinventiomand desire to secure by Letters Patent, is-- v 1. The within-described production 'of'thiclr varnish, the same consisting offrefined petro-v leum and vresin or resinous gums, the latter in. very large proportion,-with or without the ail dition-of soap, the ingredients being agitated together at the temperatures designated, as

and for the purpose herein set forth.

2. The'.within-described, produetion'of thin varnish, the some consisting, tirs'u'of refined petroleum and resin'or-resinou's gum, the latter in very'largeproportiomwithor without the addition of soap, and ultimately of a much-larger proportiouof petroleum, the ingredients be ing agitated at-the temperatures designated, while-the proportion of petroleum is small, then cooled and subseq'uently again agitated at the moderate temperaturesdcsignated, as and for the purpose herein set forth;

3. The use 'of soap, in combination with petroleum-and resin or re the purposeset forth.
